[Prior art]

 Computers have already become a necessary equipment for modern people or companies, and the user's emphasis has also been placed on the operating speed of the computer's CPU. However, if the operation speed of elements such as a CPU, a printer, or a chip is increased, overheating of the temperature is surely formed, and the CPU or the chip may be burned. In order to effectively lower the temperature of the CPU, a method of dissipating heat by mounting an aluminum press heat sink and a fan on the CPU has been adopted. However, as the operating speed of the CPU further increases, the rotational speed of the fan must be increased to perform rapid heat dissipation. In addition, it is easy to assemble and disassemble. To fix the aluminum press heat sink and the fan to the motherboard firmly, apply adhesive to the CPU to fix the heat sink and the CPU, or fasten the heat sink to the CPU socket with fasteners. The method has been adopted. However, as shown in FIGS. 1 and 2, the structure of the fastener of the known heat sink includes an L-shaped locking rod 10 'formed by bending an elastic steel material, and the L-shaped locking rod 10'. The horizontal rod 12 'extends vertically from one end of the horizontal rod 11', a locking means 13 'is provided at an end of the vertical rod 12', and a hook portion 32 'is connected to the other end, and It has a curved shape. This can lock the heat sink to the CPU socket, but has the following disadvantages because the L-shaped locking rod 10 'is formed by bending an elastic steel material. 1. The main body is made of an elastic material, and it has the disadvantage of unstable deformation during heat treatment. 2. When a vibration is formed due to a drop or impact, a vertical and horizontal resonance force is generated, and a falling phenomenon occurs. 3. Different models often have different heat sink standards, so new molds had to be manufactured, which was expensive.

Actively mounted on the L-shaped locking rod holder, and the locking lever is convenient for assembly and disassembly.

It is another object of the present invention to provide a kind of heat sink fastener structure, in which reinforcing ribs are formed on both sides of an L-shaped locking rod, and the L-shaped locking rod is provided. Shall strengthen the pad and position the elastic means.

A further object of the present invention is to provide a kind of fastener structure of a heat sink, which is provided with a chamfered portion at both ends of the reinforcing rib on both sides of the mounting portion, and in the mounting portion. A convex point is provided and combined with a convex portion provided in the mounting hole of the detachable rod, whereby the detachable rod is actively mounted on the L-shaped locking rod, and the detachable rod does not fall off. Assembling and disassembly are easy.
